AC mains voltage supply cables should meet local and national regulations. LeakFilm MC
power supplies will accept wire sizes in the range 0.5 – 6 mm
(stranded core), or 22 – 12 AWG. Wire temperature ratings should be minimum 80 °C and
wires should be tightened to 11.9lb-in torque.
For terminals (CON16, J11, J7, J8, J2, J3, J4 and J5), LeakFilm MC will accept wire size in
the range 0.13 ~ 2.0 mm
minimum 80 °C and wires should be tightened to 3.5lb-in torque.
